WEED-PULLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 328,71 dated October 20, 1885.

Application filed June '23, 1885. Serial No. 169,603. (No model.)

To all whom it may concern:

Be it known that I, EDWARD LEWIsRAs- MUSsON,of Duluth, in the county of St. Louis and State of Minnesota, have invented a new and Improved WVeed Pulling Machine, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved machine for pulling out weeds by the roots.

The invention consists of two sets of revolving wheels provided with an endless chain and spurs, of a recessed frame through which pass the chains and spurs to clamp and pull the weeds, of a device for imparting a rotary motion to the chain-wheels from the main axle, and of an adjustable swinging frame provided with handles and an adjustable dragging wheel.

The invention also consists of various parts and details hereinafter more fully set forth and described. Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figurel is a side elevation,partly in section, of my improvement. Fig. 2 is a plan view of the same with parts broken out. Fig. 3 is a vertical cross-section on the line as w of Fig. 1. Fig. 4 is a cross-section on the line 3 y of Fig. 1, and Fig. 5 is an under side view of the pulling device.

The driving-wheels A A are secured to the axle B, which is mounted on the main frame 0 of any suitable construction.

The beveled gear-wheel D is fastened on the axle B by means of a set-screw, and meshes into the beveled gear-wheel D, provided with the beveled gear-wheel D ,which meshes into the beveled gear-wheel E,placed on the end of the shaft E. The gear-wheel D is placed on the shaft D which is supported by the axle B and the frame D.

The frame F is pivoted on the shaft D,and is provided with the handles F to guide the frame F, carrying the weed-pulling attachment. The rear end of the frame F is provided with the bar Fipivotally attached to the frame F, and the clamping piece L, and havinga dragging wheel, F which is adjustable on the bar F The shaft D and the frame D swing on the axle B, and the frame F, being pivotally attached to the shaftD fiforms thereby a universal joint, which allows the operator to 5 5 wheel G is secured to the shaft G,and meshes into the spur-wheel Gflattached to the inclined shaft Gflwhich has similar hearings to shaft G. The shafts G and G are each provided on their lower ends with the wheels I, each connected to similar wheels, J, revolving on shafts J, placed on the frames H, by the chains K, provided with projecting pins 70'.

From the cross-piece F of the frame F extends downward the beam F",to the lower end of which is secured the clamping-piece L,pro-

vided with the recesses L on each side,througl1 which pass the wheels I and the chains K with their projecting pins K, in such a manner that the weeds are drawn into the recesses L and clamped therein by the chains K and projecting pins K.

From the clamping-piece L and between the frames H extends upward the guide M, attached on the upper end to the frame F, and to the frames H are secured the curved guides M,

which, in connection with the center guide,M,

facilitate the removing of the pulled weeds.

The operation of this machine is as follows:

A rotary motion is imparted to the wheels I and J from the main axle B on the forward movement of the entire machine by means of the beveled gear-wheels D, D, D and E,causing the shafts E and G to revolve, and the spur-wheel G, meshing in the spur-wheel Girotates the shaft G placed near the ground by adjusting the dragging wheel F on the shaft F and on account of its pointed front feeds the weeds to the recesses L, in which they are clamped by the projections K and the chains K, and pulled out 100 of the ground by the forward motion of the entire machine and the slower upward motion The 60 The clamping-piece L is of the endless chains K. The latter carry the weeds now upward between the guides M and M, and on reaching the upper end they pass from the guides M and M, and fall to the ground in the rear of the clamping-piece L. The chains K run at a lower speed than the forward motion of the machine, so that the latter motion will cause a direct draft on the clamped weeds in the clamping-piece L, and the chains K will elevate the pulled weeds,as before described.

The driving-gear on the axle Bis adjustable on the latter by means of a collar, N, and setscrew N, so that it can be shifted to one side or the other near one of the driving-wheels A.

, The latter can also be made adjustable on the axle to any desired width.

The operator is enabled to swing the frame F and its attachments sidewise or raise and lower the same by means of the handles F.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a Weed-pulling machine, the wheels I and J, the chainvK, and the projections K, in combination with the clamping-piece L, having the recess L, substantially as shown and described.

2. In a weed-pulling machine, the wheels I and J ,the chains K, and the projections K, in combination with the pointed clamping-piece L, having the recesses L,and the guides M and M, substantially as shown and described.

3. Ina weed-pulling machine, the wheels I and J, receiving a rotary motion by suitable connections from the axle B,the chains K,the projecting pins K, the clamping-piece L,having the recesses L, and the guides M and M, in combination with the adjustable dragging wheel F,and shaft Fflpivotally attached to the frame F,substantially as shown and described.

4. In a weed-pulling machine, the wheels I and J, the frame H H, supported from the main frame F, the chains K, the projecting pins K,

the clamping-piece L, having recesses L, and the guides M and M, in combination with the adjustable frame F, substantially as shown and described.

5'. In a weed-pulling machine, the axle B,

a rotary motion to the wheel I, substantiallyas shown and described.
